Image: Summary: A rollercoaster is a perfect model, or example, to understand and learn about potential energy, kinetic energy, and more. Our rollercoaster goes through many twists and turns giving the people a fun ride that also comes to a safe and complete stop. First, our rollercoaster loops around a dowel forming a turn as it goes downhill in order to build up enough speed to climb up the hill. Then, it goes up and down the hill into a loop that slowly flattens out to bring the marble to a stop. Since the initial drop is not counted as a hill, at least one turn or loop has to come before the hill so the marble can gain momentum. In our rollercoaster, the marble has the most potential energy right before it is dropped (while it is held atop the rollercoaster) and has the least amount when it comes to a stop because those are the places in which the height of the rollercoaster is the tallest and shortest. Finally, I noticed that the height at which the hill is placed can

Image:  Summary:  A model is an example, most typically a smaller version, to represent a system so you can understand how it works. A moedl rollercoaster is the perfect tool to understand and learn about potential energy, kinetic energy, and more. A system is a group of parts that work together to make a whole end result. The parts of the system that make up my groups rollercoaster include; two loops, two turns, and one hill. The system is arranged as seen above because the initail drop cannot count as a hill, meaning that there must be at least one turn before the hill so the marble can gain momentum to 'climb up'  the tubing. Potential energy is energy stored up and is waiting to be used, and is based on the position of an object, the elasticity or the chemical makeup. In this case, the marble has the most potential energy at the top of the roller coaster(beginning) because that is the highest point, meaning the height is the highest. This in turn effects the potentia

Actually, there are two main branches of energy consisting of kinetic and potential energy. Kinetic energy is energy an object has because it is in motion whereas potential energy is energy that is waiting to be used hence the name potential. Potential energy itself branches down into three groups including gravitational potential energy, elastic potential energy, and chemical potential energy. Gravatational potenttial energy is potential energy due to an objects position. An example of this would be a boulder sitting high atop a mountain. Elastic potential energy is potential energy due to the compression or expansion of someone or something. For instance, stretching a rubber band without releasing it would be elastic potential energy. Chemical potential energy is potential energy that is held within the chemical bonds of an object or substance. A form
